The Rumpler C.VII was a reconnaissance aircraft from Rumpler-Werke GmbH . The C.VII, published in 1917, achieved particular importance as a long-range reconnaissance aircraft with radio equipment and as a photo reconnaissance aircraft.
history
The C.VII was the third Rumpler reconnaissance aircraft, along with the C. III and C.IV, to achieve impressive production figures. Since the aircraft fuselage remained essentially the same for all models, the models can only be differentiated on the basis of the different engine cowlings. The two-legged, fabric-covered double - decker was designed by Edmund Rumpler and over 1000 copies were built from 1917 to 1918 in the main factory and in Augsburg at Bayerische Rumpler-Werke AG .
The good altitude performance gave her a certain security against the enemy fighters.
construction
The dimensions of the C.VII are sometimes described in the literature as being different from those of the predecessor models of the Rumpler C series. With the airframe, however, the dimensions remained practically unchanged compared to the previous models in the C-series. The length changed by only the lower length of the Maybach compared to that employed in the C.IV Mercedes D.IVa .
In addition to altitude recorders , oxygen systems and heated flight suits , the equipment also included a handheld camera. The plywood propeller was 3.10 meters in diameter and had no hub fairing. The aircraft was designed for a service life of six hundred flight hours.
The liquid-cooled six-cylinder, four-stroke in-line Maybach Mb IV engine with 240 hp and two floatless Maybach carburettors, manufactured by Maybach-Motorenbau in Friedrichshafen , ensured better flight characteristics with its higher compression compared to the previous C.IV.
Use in Switzerland
A copy with the military matriculation 702 was used by the Swiss Air Force from 1920 and was intended to be used primarily as a high-altitude training aircraft. As early as May 18, 1920, the device suffered a serious accident with a total write-off. Examinations carried out after the fact came to the conclusion that the maintenance personnel had incorrectly connected the aileron control cable. The pilot got away with minor injuries.
